PID The following occurred at approximately 8:00 PM on May 16 which lead to delays in starting a BOP test. Once the hydraulic fittings were repaired, the remaining BHA was pulled out of the hole( 2 stands of 5" HWDP & 3 stands of drill collars) The BOP test didn't start until 2:30 AM on the morning of the May 17 when it should have started on May 16 "While pulling out of the hole with 4" Heavy weight drill pipe, the driller was powering up with the draw works and in anticipation of the crossover sub to the 5" heavy weight drill pipe coming to the rotary table, stopped applying power to the drawworks and subsequently the inertia from the machinery and pipe in hole caused the pipe to continue coasting upwards until the 4" HT -38 x 5" NC -50 crossover hit the drill pipe guide shoe. The PS -21 hydraulic slips were lifted free from their placement in the rotary table and continued upward for an additional —4'. The hydraulic connections supplying power to the PS -21 hydraulic slips were torn apart and approximately 4.5 gallons of hydraulic fluid was sprayed onto the rig floor. The rig floor hydraulic pump was shut off by the driller and the 1/4 turn ball valves on the piping to the PS -21 slips were manually closed to stop the hydraulic fluid flow. Approximately 4.0 gallons of hydraulic fluid drained into the rig floor drip pan and was contained there. The remaining 0.5 gallon was cleaned up with hand tools and absorbent and the absorbent was bagged and disposed of as oily waste." The PS -21 slips were lowered back into place in the rotary table. The released hydraulic oil was cleaned up and the damaged hydraulic system fittings were repaired.

K-1 OB was a CTD side-track drilled in December 2003 targeting Sag River sands. The well was POP'd 01/08/2004 and produced all gas~ An ASRC portable separator was brought in and confirmed the W PS data. A liner top test plug was run. Subsequent tests indicated no change in gas rates and that the liner top was not leaking. A CNL-Borax log was run and confirmed that there were no cement channels behind pipe an~/~,b_~ Sag interval that was targeted was depleted. The well has remained SI since May 2004. /' The Ki1/~'~~idetrack is scheduled for Doyon rig 16. Current estimates have it beginning around December 1 0, 2Ó~~lowing the completion of well V-212i. The pre-rig work for this sidetrack is planned to begin as soon as the attached Application for Sundry is approved.
